Key Features
- 1.27mm pitch male board connector in the M50 series enables high-density PCB-to-PCB mating in space-constrained assemblies
- Brass contacts with tin (Sn) over nickel (Ni) barrier plating deliver reliable low-resistance mating and corrosion resistance
- RoHS-compliant construction supports green manufacturing and export compliance for global electronic product designs
Applications
The M50-3651342R is used in compact board-to-board interconnect applications within industrial instrumentation, medical devices, and consumer electronics where a 1.27mm pitch saves significant board real estate compared to 2.54mm alternatives. Its male brass-contact design mates with corresponding Harwin M50 female receptacle connectors, providing a reliable mechanical and electrical link for signal and low-power connections in multi-board system assemblies.

Frequently Asked Questions
What pitch does the M50-3651342R use and why does that matter for board space?
The M50-3651342R uses a 1.27mm contact pitch, which is half the spacing of standard 2.54mm through-hole connectors. This tighter pitch reduces the footprint of a 34-contact connector by roughly 50%, making it ideal for dense PCB layouts in medical handhelds, portable instruments, and compact IoT modules where every square millimeter of board space counts.
What contact material and plating are used, and how do they affect the connector's long-term reliability?
Contacts are made from brass with a nickel (Ni) barrier layer followed by a tin (Sn) mating finish. The nickel barrier prevents tin from diffusing into the brass substrate over temperature cycles, maintaining contact resistance below typical thresholds of 30 milliohms throughout the connector's mating life. This combination is standard in industrial-grade board connectors that must withstand hundreds of mate-unmate cycles.
Is the M50-3651342R compatible with other connectors in the Harwin M50 series?
Yes. The M50 series maintains a consistent 1.27mm pitch standard across male headers, female receptacles, and mixed-gender variants, so M50-3651342R male pins mate directly with M50-series female connectors of the same pin count and row configuration. This family compatibility allows mix-and-match sourcing for multi-board assemblies while ensuring mechanical and electrical interoperability at 1.27mm spacing.
Does this connector meet RoHS environmental compliance, and can it be used in products sold in the EU?
Yes, the M50-3651342R carries a RoHS-compliant designation (Pbfree Code: Yes), meaning it is free of lead, mercury, cadmium, and other restricted substances under EU Directive 2011/65/EU. Products incorporating this connector can bear the CE mark for electrical equipment and be shipped into EU markets without additional hazardous material declarations for this component.
